New here and can really use some help. This might not be the right section to post this but i figured id have better luck here. I just recently finished swapping a 24v into my ford and have been having a problem getting it to start. Before I say this my heater grid is not hooked up and i know its horrible on the motor but the truck will only start with a small hit of ether.Once its started it runs perfect. Idles great sounds smooth and revs up like it should.Once you shut it off and try to start it right back up it wont start. It wont even sputter or sound like its trying to start. The vp44 is brand new and was part of the problem originally when i first started trying to start it. It has since been pulled off and sent back to find it had a defective computer on it. It was repaired and sent back to me but the truck still will not start without ether. I also just sent the ecm off to be checked and they found it had a bad apps and lift pump circuit. It was repaired and sent back and still the truck will not start without ether. Before the ecm was sent off I had a few codes. p0122,p0237,p0336,p1287,p1689. Now that the ecm was repaired im seeing no codes.I also replaced my brand new crank sensor with another brand new sensor just to be sure and still no change. Fass pump cycles on like it should with key on and im getting good pressure at the pump. If anyone has anything they think i can try or check please let me know. Ive been testing wiring and sending parts off for the past two months and im at my breaking point. Thanks for the help.

I do have the Cummins pcm installed and hooked up. I’ve used my code reader and have pulled several codes before the ecm was sent off and now it’s still throwing the same codes after repair plus a new one. Codes are p0122, p0123,p0222 (new code)

p0237,p0336,p0380,p0382,

p1287,p1689,p1698

 

Note that I do not have the grid heater hooked up. 

Were the old codes ever cleared to see if they come back?

The truck should start without lift running unless something is preventing the fuel from being pulled out of the tank. Mine still ran and drove after 2 seperate lift pump failures. Mine is an Air Dog but them and FASS are not that much different.

I cleared them twice and they come back. The vp44 only runs when wired to battery. It might not have pulled fuel on its own since I was still trying to bleed it. With the vp wired to battery it would try to start with the fass connected to 12v but not connected to lift pump plug. Also it will not attempt to start at all with the stock harness connected to the vp. 

What codes?

 

Still need to know about WTS light?

Codes are listed above. I won’t be able to check the WTS light till tomorrow. I’m on duty at the fire station and won’t be home till tomorrow.
